Does this combination of features allow me to add 3× my Charisma to my AC?

Paladin 1, smite evil (deflection):

In addition, while smite evil is in effect, the paladin gains a deflection bonus equal to her Charisma modifier (if any) to her AC against attacks made by the target of the smite. If the paladin targets a creature that is not evil, the smite is wasted with no effect.

Sword-devil 4, untouchable (untyped):

Untouchable (Ex): At 4th level. the sword-devil’s confidence and personality distract her foes in combat, making her more difficult to hit. When unarmored and unencumbered. the sword-devil may add her Charisma bonus (ifany) to her AC and her CMD.

Osyluth Guile feat (dodge):

Benefit: While you are fighting defensively or using the total defense action, select one opponent. Add your Charisma bonus to your AC as a dodge bonus against that opponent’s melee attacks until your next turn. You cannot use this feat if you cannot see the selected opponent.

According to Paizo, bonuses of the same type (except dodge) don’t stack. There you have three different bonuses so, apparently, they should stack, which looks pretty strong.

Am I missing something?
